New decoration process for a sustainable society

Films for automotive exterior

TOP

Environmental-friendly decorative films

As society rapidly moves towards sustainability, including reducing CO2 emissions, the mobility industry is also showing rapid changes such as the spread of electric vehicles.
In current automotive production the painting processes (including drying) emit higher levels of CO2, and so placing with environmentally friendly alternatives is drawing market attention.
One alternative method is decorative films for the exterior.

Nissha value proposition
(Film Insert Molding)

Our decorative film technology allows graphic patterns (including function) on the part surface through an in-molding process. This process is simplified compared to conventional paint and chrome plating, resulting in less environmental impact.
In addition, it allows a wide range of graphic patterns and designs, that cannot be achieved with paint and chrome plating alone, to include functions like back-lighting or heating.

No drying process

for film insert molding is required unlike for paint or chrome plating.

No top coating process is required

after forming, because of surface properties of the film.

Applications Targeted such as

Bumpers, grilles, and pillars.

Nissha has a long history of decorative film solutions for global automotive interior décor parts, such as door trims, consoles, and display covers. We now extended our know-how to the exterior décor market.

Process

Printing

For IML films, both gravure printing and silk-screen printing processes are available in Nissha. We select the best way according to the design specifications and production volume.

Film preforming

The films are inserted into the mold and formed through high heat or pressure.

Film trimming

We trim the film surroundings with a die-cutter or laser.

Film insert molding

The formed IML films are inserted into the injection mold tool to form a heat bond with the resin.
After injection molding the decorative parts are complete.

CO2 reduction initiatives

*by use of renewable energy

Looking towards achieving carbon neutrality by 2050, Nissha aims to reduce its total CO2 emissions by 30% (compared with 2020) by 2030. Our printing factory for decorative film in Japan switched to using entirely renewable energy as of January 2022. This has enabled approx. 28% reduction in CO2 emissions per product area.

Parts for proposal

Realization of diverse designs

Various designs can be realized that cannot be achieved through painting.
The possible designs include metallic finishes, carbon-fiber patterns, and geometric designs, and furthermore, on the back surface of molded products, it is possible to achieve hidden-til-lit designs that incorporate LED light sources.
Through our in-house CMF Design Team, we at Nissha propose high-quality designs while listening to the requests of customers. We ask for customers to first of all let us know what they would like to do.
